AUTOMATIC CORN-CRIBBER.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed January '7, 1907. Serial No. 351,076.

To all whom it may concern:

Be it known that I, MYRON L. IIUnD, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Automatic Corn-Cribbers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My present invention relates to an automatic corn cribber, and has for its object to provide an apparatus of that class, by means of which a wagon-bed containing corn or the like, may be lifted from its running gear and conducted to an opening in the crib or bin and emptied thereinto, means being provided for automatically opening and tripping the wagon bed in order that the contents may be transferred from said bed to the bin.

A further object is to provide the improved details of structure which will presently be fully described and pointed out in the claims, reference being had to the accompanying drawings forming part of this specification in which like reference numerals refer to like parts throughout the several views, and in which,

Figure I is a view in side elevation of an apparatus constructed according to my invention, showing a wagon and lifting apparatus. Fig. II is a similar view showing the apparatus with the wagon-bed in its dumping position. Fig. III is a top plan view of the apparatus with the wagon removed. Fig. IV is a view on the line IVIV, Fig. I, with the wagon removed, but showing the wagon cross pieces which are engaged by the lifting frames. Fig. V is an enlarged detail view of the lifting frame shaft slide. Fig. V1 is a detail view in elevation of the derrick base.

Referring more in detail to the parts,1 and 2 represent poles mounted on a base 3 and having the cross piece 4 at their top, by which they are united to form a derrick frame, such frame being mounted in close proximity to a crib in which it is desired to unload the corn, a portion of such crib being shown and indicated by the numeral 5. Extending through poles 1 and 2 near the top is a shaft 6, and revolubly mounted on said shaft are the beams 7 and 8, provided with slots 7 and 8, and having at their outer ends a spreading bar 9. Extending through and adapted to ride in the slots in beams 7 and 8 is a shaft 10 which is revolubly carried in the outer ends of the arms 11 and 12, said arms being revolubly mounted on a shaft 13 extending through and carried by the poles 1 and 2.

On each of beams 7 and 8 is ashort rack 14-15, and rigidly secured on shaft 10 and adapted to travel in said racks are the spur wheels 1415, the racks and spur wheels being located on the outer sides of beams 7 and 8 so that after leaving the racks, the spurs of said wheels will not engage the beams, but the shaft itself engage the beams and support the parts depending therefrom. Arms 11 and 12 are provided with the spreading bars 16 and 17, and the poles 1 and 2, with a number of perforations at different heights in order that said arms may be raised or lowered for a purpose presently set forth.

18 is a wagon bed carried on a suitable running gear, which is shown, but not specifically mentioned herein, and projecting from each side of said bed and rigidly secured thereto are the cross bars 19 and 20. On each side of the wagon bed is a lifting frame, each of which frames is provided with a base 21 adapted to engage the under side of the portion of each of the cross bars 19 and 20, which projects beyond the wagon bed, and having the side arms 22 and 23 which extend upwardly and inwardly and are rigidly secured together at their apex; the rear bars 23 being provided with a forwardly angling portion 24 provided with a slot 25 in which a shaft 27 is adapted to travel. Revolubly mounted on shafts 27, 10 and 6 are a number of sheave wheels. Rigidly secured on the forward bars 22 of the lifting frames are the eye-bolts 28 and 29, to each of which is attached one end of a rope 30-31, which ropes extend upwardly over one of the wheels on each side of shaft 1.0, downwardly to engage a similar wheel 82 on shaft 27, up over a second wheel on shaft 10, down over a second wheel on shaft 27 up over a wheel on shaft 10, rearwardly to a wheel on shaft 6, back over a fourth wheel on shaft 10, rearwardly over a second wheel on shaft 6, from thence downwardly to the bottom of the derrick and after engaging the guide wheels 33 and 33 are secured in a ring 34, from whence a draft chain or rope '35 extends outwardly and is provided with a ring or clevis 36 to which a draft apparatus may be attached.

Pivoted on the outer side of each of the vertical side arms of the lifting frame is an car 37 having an outwardly extending flange 38, and pivoted to each of said cars is a lever arm 39. The lever arms on the front and rear side arms of each frame extending toward each other and each being pivoted to an upwardly extending bar 40,. having notches therein adapted to lock against a bracket 41. This apparatus being used to lock the lifting frame firmly to the wagon cross bars 19 and 20 and to release same in the manner illustrated.

42 represents the wagon-bed end gate which rocks on a shaft carried by the bottom of the wagon, and 43 is a pulley carried by said end gate.

44 is a rope attached to the crib and having means on its free end by which it is attached to the wagon running gear, for a purpose presently described.

-When in use the parts are arranged as described, and a wagon containing corn driven to the position shown in the drawings and the lifting frame lowered to bring the lifting bars 21 beneatli the wagon cross bars 19 and 20. 'lfhe clamps carried by the arms of the lifting frames are then rocked against the upper faces of said cross bars, and locked in such position by securing the upper notch of bar 40 in bracket 41. The horses are then unhitched from the Wagon and hitched to the ring 36 of the draft chain. By drawing said chain outwardly, the ropes 30 and 31 are drawn downwardly lifting the wagon bed from the running gear and at the same time causing shaft 10 to travel upwardly in the slots in beams 7 and 8. To prevent the shaitlO from traveling too rapidly in said slots, the rack 16 is provided for the beams and the spur wheels 15 provided for shaft 10 so that the inward travel of said shaft is retarded until after the wagon bed is free from the running gear. After the bed has been lifted from the running gear, the movement of the ropes tends to simultaneously lift said bed and draw said shaft inwardly, and the latter being carried by the arms 12, said arms are also drawn upwardly and owing to their length, causing an upward movement of beams 7 and 8 until the parts reach the position indicated in Fig. 11. During the upward travel of the wagon bed, the pulley on the end gate of the wagon travels along rope 44 until when it reaches the elevation shown, the rope is drawn taut, causing a downward tension on said gate until the latter is drawn back and swung downwardly until its outer end is partially within the opening in the crib. If so desired a spring catch or like fastening may be provided for yieldingly retaining the gate in a closed position, until opened as described. Simultaneously with this operation of the end gate the rear end of the wagon bed is drawn downwardly causing the shaft 27 to travel in slots 25 to bring the bed into the position indicated in Fig. 11, when the contents of the bed' will flow out of the end gate into the crib After the wagon' has been emptied in this manner the parts are lowered until the bed again rests on the running gear, when the wagon is backed away from the bin or crib to make room for another load. As it is necessary to dump the wagon from the end adjacent to the crib, I find it advisable'to reverse the bed on the running gear so that the wagon may be driven up to theposition shown in Fig. 11, although it may be backed up if desired. By seating the shaft 13 to the different sockets in the derrick poles the arms 11l2 may be raised and lowered to adjust the parts to the height of the crib opening or to allow them to reach various openings.

While 1 have described my inventionas an automatic corn cribber, it can readily be seen that the apparatus may be used for unloading other produce or may be used to advantage in unloading coal or like matter. 7

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent is,

1. In an apparatus of the class described, the combination with a wagon having a bed provided with cross bars, lifting frames adapted to engage said bars, means for raising said frames, and a rocking arm for guiding said frames to a desired position.

2. In an apparatus of the class described, the combina tion with a support and traveling beams, of a lifting mechanism comprising a pair of lifting frames having slotted members, a shaft extending through and adapted to travel in the slots in said members, and supporting said mechanism by means connecting same with said traveling beams.

In an apparatus of the class described, the combination with a support and traveling beams, of a lifting mechanism comprising a pair of independent frames, each having a slotted member, a shaft loose in said slots, ropes connecting said shaft and traveling beams anda locking device for connecting said frames, and ,anobjectwith which they may be connected.
